Dental caries-associated oral streptococci are called the mutans streptococci, with Streptococcus mutans and Streptococcus sobrinus being the most prevalent caries-associated organisms in humans. Strains of the mutans streptococci are highly conserved within not only mothers and their children but also racial groups, suggesting vertical transmission of this organism within human populations. It...

The objective of this study was to investigate the ability of biofilm formation among mutans and non mutans oral streptococci and to determine the effect of Lactobacillus acidophilus DSM 20079 as a probiotic strain on the adhesion of selected streptococcal strains on the surfaces. The sample comprised 40 isolates of oral streptococci from dental plaque and caries of volunteer persons. Streptoco...

Mutans Streptococci, in particular S. mutans and S. sobrinus, are generally considered to be the prime etiological bacteria of human dental caries. The aim of this study was to determine the frequency of mutans streptococci in dental plaque in three groups of caries-free and caries-affected Venezuelan children aged 2-6, 7-12, 13-19 years, and their possible association with dental caries. The f...

PURPOSE The purpose of this study was to examine the effects of maternal dental health education and tooth-brushing instruction on the levels of mutans streptococci in pre-school children. METHODS One hundred and seven children (44 boys and 63 girls) with a mean age of 20.5 months, randomly selected from a community child health clinic within a 2-week period, participated in this study. Medic...

BACKGROUND AND OBJECTIVES The counts of cariogenic bacteria lactobacilli and mutans streptococci have been studied and correlated with sugar intake. This study was to investigate the association between salivary lactobacilli and mutans streptococci counts with sweet food eating behavior and sweet sensitivity among 120 Malaysian women (101 ethnic Chinese, 19 ethnic Indians), while taking into ac...

The aim of the present study was to compare the recolonization pattern of mutans streptococci on densely colonized teeth with and without fixed orthodontic appliances after treatment with a 40 per cent chlorhexidine (CHX) varnish (EC 40, Explore). Healthy subjects free of carious lesions requiring fixed orthodontic appliance treatment but with high bacterial mutans streptococci saliva counts we...

Reducing the burden of pathogenic mutans streptococci is a goal of oral health. Lactobacillus paracasei DSMZ16671, even after heat-killing, specifically co-aggregates mutans streptococci in vitro and retains this activity in human saliva. In rats, it reduces mutans streptococcal colonization of teeth and caries scores. This pilot study sought to assess the potential of heat-killed L. paracasei ...

in the recent years, herbal oral hygiene products have gained increasing attention. the aim of this study was to assess the effects of three types of mastic gums on the level of mutans streptococci, lactobacilli and ph of the saliva.forty-two students in the age range of 20-30 years were divided into three parallel groups; each of them separately used pure mastic gum, xylitol mastic gum and pro...

Purpose: The aim of this study is to evaluate the clinical efficacy and safety of a new dental drug delivery system (3DS) for the selective reduction of mutans streptococci, a potent risk factor for dental caries. Materials and Methods: Twelve patients were assigned to two groups, professional mechanical tooth cleaning (PMTC) with or without 3DS. The efficiency of 3DS with 0.2% chlorhexidine (C...

The heterogeneous group of oral bacteria within the sanguinis (sanguis) streptococci comprise members of the indigenous biota of the human oral cavity. While the association of Streptococcus sanguinis with bacterial endocarditis is well described in the literature, S. sanguinis is thought to play a benign, if not a beneficial, role in the oral cavity. Little is known, however, about the natural...
